Assessment of Patterns and Trends in Alaska Fire Severity

Submitted by atripp on

Wildfire activity in Alaskan boreal forests has been increasing in extent and frequency over the past two decades.  These shifts have critical consequences for future fire and resource management since fire is a dominant driver of numerous interrelated aspects of the boreal environment, such as soil erosion, permafrost dynamics, carbon sequestration, wildlife habitat availability, the rate and nature of vegetation recovery, and the provision of subsistence resources.  The pote

The USGS UMESC used a combination of high-resolution digital aerial photography, MODIS satellite-derived chlorophyll concentration data, MODIS sea surface temperature data, satellite transmitters, and geolocator tags to monitor waterbird use of the Great Lakes.  These data are being used by USGS to identify key waterbird habitats on the Great Lakes, conduct impact assessments of near-shore and off-shore wind turbine placements, and elucidate factors that influence the outbreak of type-E avian botulism.
